Paraphrasing is good because you can express the same thought in multiple ways in natural language. Repeating the words is something a tape recorder can do, paraphrasing means going WORDS → MEANING → WORDS, so, if the last step is correct, the middle one is likely to be correct too. For example F = ma → reality of motion → so you say ohh like when you slide a lot on ice on rollers because there is so little friction (force)
